Specifically, the circuit-breaker halt for a Level 1 (7%) or Level 2 (13%) decline occurring after 9:30 a.m. Eastern and up to and including 3:25 p.m. Eastern, or in the case of an early scheduled close, 12:25 p.m. Eastern, would result in a trading halt in all stocks for 15 minutes. If the market declined by 20%, triggering a Level 3 circuit-breaker, at any time, trading would be halted for the remainder of the day.
